MIL 1760 is a Department of Defense Interface Standard, developed to reduce the proliferation of interfaces between aircraft and their stores, and instead to promote interoperability between weapons and aircraft platforms.

The original version of MIL 1760 defined a standardized electrical interface and connector that included both digital and analog databuses, a standardized message protocol (MIL-STD-1553), power, and discrete signals.

In 2007, the latest version of MIL 1760 was released. MIL1760E, employed the previously unused High Bandwidth 2 and High Bandwidth 4 pins of the standardized MIL 1760 connector.

These pins were utilized to carry a Fibre Channel based high speed digital databus, FC-AE-1553 which is an adaptation of MIL-STD-1553 for Fibre Channel.

Today there are several different groups of MIL1760 signals:

  • MIL-STD-704 power connections
  • MIL-STD-1553 data communications interface
  • High and low bandwidth analog signals
  • Discrete signals
  • Fiber optics

In common practice, an aircraft will support most of the MIL 1760 signals, whereas the store needs to accommodate only those signals it needs to perform its mission. As a result, stores typically use only a subset of the MIL 1760 signals.

MIL 1760 was intended to support both current needs as well as to provide growth capability as the technology matures. MIL 1760 defines a Class I aircraft interface, which has four high bandwidth and two fiber optic interfaces, and a Class II interface, which has only two high bandwidth and no fiber optic interfaces.
